Problems solved by technology

If the current cell measurement technology is used for cell measurement, only the same-frequency or different-frequency relationship between the main carrier of the adjacent cell and the operating frequency of the UE can be determined, and the inter-frequency cell determined by this method is not accurate. If the above method is determined The inter-frequency cells in the inter-frequency cell contain the same secondary carrie...

Embodiment Construction

[0035] The core idea of ​​the present invention is: in order to further improve the capacity of the TDD system, a multi-carrier cell network mode is introduced, which leads to the inability to accurately measure cells in existing specifications. When measuring the adjacent cells of the UE, the present invention not only configures the cell with the same primary carrier frequency Neighboring cells with the same carrier frequency are also configured in the same-frequency cell information list. In this way, the UE can directly use the cell information list sent by the system to eliminate co-channel interference, and the terminal can obtain accurate carrier frequency information of adjacent cells through the system cell information list. The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

Abstract

The invention discloses a method for collocating neighbor cell list in a multi-frequency cell system, which relates to the neighbor cell list collocation technique and aims at solving the problem that the collocation of neighbor cell list is not suitable for the UE. The adopted technical proposal includes the following steps: the neighbor cell measurement is carried out according to the work carrier-frequency of the UE at the user terminal; the neighbor cell of which the main carrier-frequency is different from the work carrier-frequency of the UE is collocated to the different-frequency cell information list; the neighbor cell containing the same carrier-frequency with that of UE is collocated to the identical-frequency cell list. The invention simultaneously discloses an apparatus used for realizing the method. With the invention, the UE can directly utilize the cell information list sent by the system for eliminating the interruption of the same frequency and also can obtain the accurate information of the neighbor cell carrier-frequency through the cell information list of the system.

Description

technical field [0001] The present invention relates to the configuration technology of the adjacent cell list, more precisely, relates to the configuration method and device of the adjacent cell list in the multi-frequency cell system. Background technique [0002] In the current Time Division Duplex (TDD, Time Division Duplex) 1.28Mcps system, the original technology is a single-frequency point networking situation. In single-frequency point networking, it is relatively simple for the system to measure adjacent cells. Use the carrier frequency of the UE activated cell to compare the carrier frequency of the adjacent cell. If the frequency of the cell where the UE is located is the same as that of the adjacent cell, configure it into the same-frequency cell information list. In the (Intra-frequency cell info list), if the frequency of the cell where the UE is located is different from that of the neighboring cell, it will be configured in the inter-frequency cell info list ...
